Brewing Values for Comet Hops
These are the common ranges that we've seen with Comet hops over the years. Each year's crop can yield hops that have slightly different qualities, so these number ranges are based on history.
|Alpha Acid % (AA)|
Alpha acids are the main source of bitterness in beer. Longer boil times will result in isomerization of more alpha acids leading to increased bitterness. Learn more »
|Beta Acid %Beta acids are a component of hop resins responsible for contributing volatile aromatic and flavor properties. Beta acids contribute no bitterness.||3.0-6.1%4.6% avg|
|Alpha-Beta RatioThe ratio of alpha to beta acids dictates the degree to which bitterness fades during aging. 1:1 ratios are common in aroma varieties.||1:1 - 4:13:1 avg|
|Hop Storage Index (HSI)The HSI indicates the percent of alpha and beta acids lost after 6 months of storage at room temperature (68°F or 20°C).||33% (Fair) 0.326|
|Co-Humulone as % of AlphaLow cohumulone hops may impart a smoother bitterness when added to the boil as opposed to higher ones that add a sharper bitterness to the final beer. Learn more »||34-45%39.5% avg|
|Total Oils (mL/100g)These highly volatile, not very soluble oils are easily boiled off, but add flavor and aroma to the finished beer when added very late in the boil or during fermentation. Learn more »||1.0-3.3 mL2.2mL avg|

Comet Hop Substitutions
If the Comet hop is hard to find or if you are simply out of it on brew day, you can try to substitute it with a similar hop. The old way of choosing replacement hops was done by experience and "feel". There is nothing wrong with that way. However, we wanted to build a data-driven tool to find your Comet substitutions.
Experienced brewers have chosen the following hops as substitutions of Comet:
Is Comet available in lupulin powder?
Yes! There is a version of the Comet hop in lupulin powder form. Comet lupulin powder is suggested to be used at about half the amount as you'd normally use with pellets. The Cryo/LupuLN2 (Yakima Chief Hops), Lupomax (Haas) and Hopsteiner products are pure concentrated lupulin powder, which add big flavor when used in the whirlpool or dry hop additions.
